I V This invention relates to a yagina-lsyringe fordouche purposes and has for its ob ect to'pi 'ov-ide, in a manner as hereinafter set forth, a syringe of such class for obtaining 'a' greater heat application than; the forms of such types of syringes now in general 'out any discomfort to the user, readilyo ian characters erated tofla'pply the douche solution, capable ofbeing sterilized, and comparatively inex- -pensive to manufacture. J

20 .iVith' the foregoing and, other objects in view the invention con'sists'ofthe novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawing, wherein is shown an embodiment of the invention, but it'is tobeunderstood that changes,variationszand modifications thereof. can be hadwhich will fall within thescope of the claims hereunto appended.

- The container 1 is compressible and extendible and is constructed from i'mper'forate soft rubber of appropriate thicknesszpossessmg sufficient elasticity to give goodsuction. Thecontainer 1 comprises a hollow bodylportion 5 of a capacityjto holdasu ifi;

cient quantity of douche solutiontofthorou'ghly extend the: vaginal ivall. fTlie'body portion, 5 is substantially semi-ellipsoidal in contour, whereby the body portion 5 tapers in opposite directions, but'the taper'ofthe' 7 upper portion of the body portion greater thanthe lower portion thereof. The body portion 5 is open at itst op and'isformect with animperforate flat bottom 6 toprovide fora'n upright posture therefor. The open top of the body portion 5"is, of appropriate diameter, to provide for an efficient discharge of the solution When the container is compressed, but the open top ofithe body portion is of less diameter than tl'iefl'flat bottom 63" At the open topof the container,

the body portion 5'l1as formed integral'there with an annular flaring coupling extension 7 of appropriate height. In vertical 'sec tion the body of the extension 7 e Xtenjds outwvardly in adirection 'from its point of joinder Witlrthe'body portion and merges tension" 7 provides means'for coupling the shoulderedneck 2 tothe container 1. i

The neck 2 is constructed from a molded,

'bodyof sponge rubber having a non-porous surfacethroughout, and s provided With adischa-rg'e canal 8 havinga 'taperedjvall,

of circular cross'section, at its inner'por-j tion and a cylindrical Wallatits outer porintoouter surfacing for the neck.- The e'xtion. The tapered partof the Wallof the v canal Sisindicated at9 and thecylindricalf part at 10. The tapered part ot the Wall of the canal 8 formsa continuation 'of the inner face of the" container 1 at the topof the latter.

the shouldered neck is of'appropriate length, that is short and ,soft, it cannot. injure the vaginal I opening or the ,infiammations of; the; V uterus,

The nozzle constructed of hard rubber ,comprises an .apertured disc l'4 which is seated "aga nst and is of the same diameter "asjthe diameterfofthe reduced end of the portion 11' of the; shouldered neck 2.-

' The tapered head'of the nozzle 3 consists of, a tapered body portion 19bit; annular cross section" having its rear edge integral with the perimeter'of the disc 14. The body portion 19at' its forward end; terminates in fa'top "piecejQOof circular contouriand which 7 "is'formed with a centrally disposed vdis-.1 .7 charge opening'21Qforthe solution; At the point ofjoinder of the body portion19 with thetop piece 2O, ;the nozzle is roundedas' at 22 to overcome any sharp corners, which might injure, theuser., The body portion 19fis formed with a series'ot. spaced slots, 23v of[appropriatewidth and which extend froma point in close p'roximity to the disc 14 to theKrounded' portion 22 of the nozzle.

of clothing or bedding. 7

The form'o-f the nozzle permits of'the in v struction to the syringe taking up all of the solution being usedy or mucus, and discharge to be'washed out of thevaginal cavity.

The protecting cap 4 is of soft rubber, is

of inverted cup shape and possesses the necessary elasticity to tightly bind the nozzle syringe, and the cap 4 can be conveniently removed when it is desired to use the syringe; The cap 4 is of a length to not only completely enclose the head piece of the nozzle but to extend upon the neck portionll of the shouldered neck 2. I

By constructing the shouldered neck 2 of sponge rubber a non-conduct0r ofheat is provided and whichwill permit-of greater heat to the internal membrane, sinceit will to; prevent leakage of the fluid in the That is to say it not only encloses thehead piece ofthenoz'zlei but also the disc 14 of the latter and further clamps against-the outer terminal part of the pornot heat the vaginal opening, which is more I sensitive than the vaginal membrane, there by giving more value to treatment, better disinfection and cleansing. The sponge rubber construction; of shouldered neck,

when the syringe is used,,will not hurt-or give pain to the user, further it molds-itself it 7 to fit the opening and vulva perfectly and overcomes the injurious objections due to hard rubber types of necks. Furthermore membrane. snugly, without pain, can be held firm enough to permit'of pressure of solution in use, sufficient to balloon 'up'the vaginal cavity thereby straightening out all'folds of the membrane, so that they arecleansed and obtain thorough medication. The solution employed can be'whatever isdesired, heated or not, it heated it can be held in thevagina as long as desired thereby getting the full-Y- est value of theyheat. andmedication', with a minimum; amount of solution and trouble,

The coating extends throughout'the outer and inner peripheries readily removed owing to the construction i The introduction of the nozzle is had without any painful effect upon the user and owing to the manner of 7 lit) of thespoi'igerubber body and ,,isl indicated at-2 5 Thefcoating is of-su'ch, thickness that Will make the neck appropriately pliable and-not-fdestroy the sponge softness, orjpr'event the neckf from shaping itself to the tissues which are in contact with it.,;:The' coating extends from the outer end of the extension 7, and also from the point of joinder of the latter with the upper end of the body portion 5.

details of construction can be had which will fall within the scopeof the claims here unto appended.
